1919. Serial gun carriage and relates further to a guncarriage forming a complete artillery unit so constructed as to permit of travel over all sorts of ground, owing to its large hearing surface on the soil, both When travels ing and when firing. This plant is particularly valuable on light or wet soils, Where the mere support of the usual gunwarriage trails becomes absolutely insufficient.

ing capable of displacementand of pivoting by mechanical control, which permits of any displacement and change of mm necessitated by a change of objective. This gun carriage consists essentially of a chassis, having supports for the trunnions of the cradle of the gun, and provided with rollers which roll over the chains actuated by driving wheels moved by a motor located on the gun carriage itself.

In the accompanying drawing, which illustrates by way of example one constructional form of the invention:

Figure .1 is aside view of a gun carriage forming the subject-matter of the invention;

Fig. 2 is a plan, some parts being removed in order to show the mechanical connections between the motor and the chains.

The gun carriage is formed by two gun-' carriage cheek beams 1 connected to one another in front and at the back by cross bars so as to form-a trough 7 between the fore part and the rear. These beams are provided with a lateral frame provided at its lower part with rollers 3 rolling on chains 4 of the type actuated by independent drivingwheels 5 at the back. Independent chain wheels 6 are arranged at front and serve to keep the chains taut.

The two cheek beams of the gun carriage l are united by front and rear floors, the front one of which is divided into two parts Specification of Letters Patent.

This gun carriage possesses the advantage of be- Patentcd June 29, 1920.

by the trough 7, which forms a re il space for the gun. Upon the rear floor is sooured, for instance by the aid of screws not shown, a motor which may be a steam, hydrocarbon or other motor, the transmission of which may control directly the toothed wheels meshing with the chains t through the medium of chains, belts or' toothed wheels, such transmission being provided with known members such as gear-box, clutch, brake.

In particular, it may be provided with a transmission with toothed hvheels, and, in

order to facilitate the driving of the carriage, with a clutch of any type for each chain 4, so that the driver may actuate simultaneously both the chains to go forward or backward, or only one of the chains to turn.-

In the example of construction shown on the drawing, 30 is the motor, for instance a hydrocarbon motor, the shaft of which bears a pinion 44 meshing with a toothed wheel 45 keyed on a shaft 33 transverseto the carriage, upon the ends of which are secured one part of the clutches 34 and. 35. The other parts of the saidclutches are mounted on the shafts of the pinions 36 and 37, which mesh with the gear wheels 38- through convenient levers, as shown diagrammatically by the arrows in Fig. 2.

In order to effect a change of o jective the gun carriage itself is actuated in such a way as to make it pivot about the rear of one of its chains in order to put it into the new direction.

What I claim is.

1. A gun-carriage. comprising a chassis having a longitudinal central opening forming' the recoil space for a gun, front and rear chain wheels carried by the chassis, a chain on each side of the chassis from the rear wheel to the front wheel, rollers carried by the chassis and bearing on the chains, a swinging gun carriage on the chase sis, a motor on the gun carriage, and means for controlling the gun carriage and imparting independent motion to the rent chain wheei'a from the motor.

2. In a gun carriage, a chassis, 1-. chain on each side of the chassis, front and rear chain wheeis. a swinging gun carriage mounted on the chassis, a motor. a iHU1- verse shaft. gearing between ihe shaft and motor. shafts carrying" pinions and, in Minement with the tl ansvel'se shaft, geniwheels carried by the rear chain wheels and mesh ing with the said pinions. and clutches, one
